54 results about "Marshalling" patented technology

In computer science, marshalling or marshaling is the process of transforming the memory representation of an object to a data format suitable for storage or transmission, and it is typically used when data must be moved between different parts of a computer program or from one program to another. Marshalling is similar to serialization and is used to communicate to remote objects with an object, in this case a serialized object. It simplifies complex communication, using composite objects in order to communicate instead of primitives. The inverse of marshalling is called unmarshalling (or demarshalling, similar to deserialization).

Method and apparatus for generating serialization code for representing a model in different type systems

In order to use object-oriented models over the Internet for applications in different type systems it is necessary to marshal and unmarshal objects between Java, SQL and XML. Hand-writing specific code to do this is difficult. A computer-implemented method of generating serialization code for representing a model in a plurality of type systems is disclosed, the method comprising the steps of: i) producing an input file from the model for a given set of objects; and ii) providing a code generator for acting on the input file to generate the serialization code.

Efficient garbage collection and exception handling in a hardware accelerated transactional memory system

Handling garbage collection and exceptions in hardware assisted transactions. Embodiments are practiced in a computing environment including a hardware assisted transaction system. Embodiments includes acts for writing to a card table outside of a transaction; handling garbage collection compaction occurring when a hardware transaction is active by using a common global variable and instructing one or more agents to write to the common global variable any time an operation is performed which may change an object's virtual address; acts for managing a thread-local allocation context; acts for handling exceptions while in a hardware assisted transaction. A method includes beginning a hardware assisted transaction, raising an exception while in the hardware assisted transaction, including creating an exception object, determining that the transaction should be rolled back, and as a result of determining that the transaction should be rolled back, marshaling the exception object out of the hardware assisted transaction.

System and method providing API interface between XML and SQL while interacting with a managed object environment

The present invention relates to a system and methodology to facilitate data communications and data management between network entities operating in accordance with various data structures and operating environments. A managed class of application programming interfaces (API) are provided that support data communications between remote / local locations employing a first data structure and a second location supporting a second data structure (e.g., API for NET languages to access SQL Server via XML views). The managed class and associated APIs provide data transformations between such structures to facilitate communications and data management among various locations and architectures. In addition, the managed class and APIs facilitate operations between disparate object systems such as between managed and unmanaged object systems via interface support of a wrapper and associated marshalling technologies to bridge communications between such systems.

Simple object access protocol

An application layer protocol is provided on top of HTTP 1.0 / 1.1 to allow for COM Automation objects to be invoked over the Internet through IIS / ISAPI servers. The format essentially encodes the automation object's name, method to invoke, and any [in], [out], [in, out] parameters that the method signature requires, packages them up into a custom MIME type and marshals it to the ISAPI dynamic link library (DLL) on the IIS / HTTP server. There, the ISAPI DLL contains the logic to unpack the SOAP request, parses it, creates the Automation object, invokes the method with the marshaled parameters, and then returns any [out] parameters to the caller / client using the SOAP protocol. It is a stateless protocol, meaning that object lifetimes only extend to one method, and are recreated between multiple calls to the object.

System and method providing inlined stub

A system and method is provided to facilitate communications between object systems. A caller is provided having optimized in-lined functionality when initiating a remote function call between managed and unmanaged object systems, for example. The in-lined functionality includes utilizing direct calls and returns within a calling function. In this manner, pushing additional arguments onto an execution stack because of an external stub reference is mitigated. In addition, one or more code loops can be analyzed to enable stack markers to be “hoisted” and thus pushed a single time instead of each time the calling function executes. Other aspects of the optimized caller provide garbage collection and thread management, security attribute checking on outgoing calls, calling convention considerations, wherein arguments and return values are organized according to the convention utilized by the remote object system, and in-lined marshalling to provide enhanced performance over external stub code references. Code extensibility options can be included enabling functions to be generalized thereby insulating object systems from implementation details of the called functions.

A set of discrete input / output (I / O) channels for one or more field devices may be grouped, organized, and connected to a field module device, which may connect to an electronic marshalling apparatus in a marshalling cabinet via an I / O channel. The field module acts as an intermediary, decoding messages received via the I / O channel to identify commands for discrete output (DO) channels that are then forwarded appropriately. The field module may also receive variable values carried by signals on discrete input (DI) channels and encode the values to a message that may be transmitted to the marshalling apparatus and controller, thus making the variable values on the DI channels available to the controller. The field module may store a profile including information that facilitates various smart commissioning techniques, including autosensing of tags, automatic tag binding, and automatic configuration of a control element corresponding to the field module.
